Maybe Not Ideal For Retirees
I´ve always been quite attracted to the idea of life strategy type funds such as LifeStrategy from Vanguard and MyMap from BlackRock´s . In fact I own both 80/20 and 60/40 funds from Vanguard. The concept of these funds is to have a mix of bonds and equities plus in the case of BlackRock a small dose of alternatives such as property all designed to provide a determined range or risk and volatility in order to meet the needs of investors at various stages of their investment life cycle. So a youngish investor who can tolerate high risk would probably go for a fund predominately invested in shares to provide higher growth but with higher volatility and someone more risk averse such as a retiree would invest in a fund overweight in bonds. The Vanguard and BlackRock funds provide low costs, diversification and automatic periodic re balancing.
BlackRock have 4 funds with different equity/bond allocations which provide varying levels of risk/volatility/return. Unlike Vanguard BlackRock can vary the equity/bond ratio in accordance with market conditions.

There are three crucial factors in drawdown which the retiree must determine: the portfolio, the drawdown strategy and the initial drawdown income. The characteristics of Vanguard´s LifeStrategy funds are directly relevant to my portfolio objectives and drawdown strategy.
Portfolio Bond Characteristics
I don´t intend to discuss the portfolio design here but any retirement portfolio is likely to include bonds as insurance to reduce volatility - but not any old bonds - they must be government bonds because only these will provide a safe have during market downturns as they are negatively correlated with share prices unlike corporate bonds which although they will show greater resilience than shares they will still decline.![]() |
Crash of 2008 - S&P 500, Intermediate Treasuries, High Quality Corporate Bonds |
At the end of 2008 the S&P 500 was down 36%, the Ishares USIG corporate bond ETF down 6% but the Ishares IEF intermediate treasure ETF was up 10%. In the majority of analyses of bond/equity portfolios the bonds are normally intermediate government bonds (7-10 years) and certainly not corporate bonds.
The bond content in the Vanguard LifeStrategy funds is a diversified mix of government and corporate bonds. In the 80% bond fund over 40% of the bond holding are non-government. I would expect this to result in higher volatility than suggested by the historical analysis published by vanguard of bond7equity portfolios. The UK LifeStrategy fund wasn´t around at the time of the 2008 crash but the US version was. This declined 14% during 2008. This is significantly worse than the performance of a portfolio of 80% Treasury Intermediate and 20% S&P500 which declined by only -3.4% over the same period (source Paul Merriman fine tuning tables).
I am sure the corporate bond holding was a major contributing factor to its poor relative performance.
Drawdown Strategy
Much publicised and much debated there can´t be many investors who are unaware of Benglen´s 4% rule and the subsequent Trinity Study. An updated version of the study appeared in an article by Wade Pau in Forbes Magazine. Maybe the rate should be 3% or maybe higher than 4% depending upon one´s risk tolerance and/or financial need however the principal is the same, a portfolio of equities and bonds which is re-balanced periodically and an initial drawdown percentage with the money withdrawn increasing each year with inflation. Providing the initial drawdown rate was not over greedy then the probability is that the pension fund will last at least 30 Years.
This is the withdrawal strategy that dominates the financial press, retirement articles, blogs etc. but it is by no means the only strategy available, nor is it clearly the best, but it is simple and certainly not the worst strategy to adopt. One of the best discussions of the various withdrawal options is by Big Erb on his Early Retirement Now blog - well worth a read. Also you can play around with different portfolio configurations and withdrawal strategies on Portfolio Charts.
I have yet to touch my investments that are allocated for drawdown - relying currently on my dividend portfolio - so I have yet to decide upon a drawdown strategy and have more homework to do before finally deciding. Prime Harvesting or a variant of it is top of my list at the moment. These strategies of dynamic stock/bond allocation use the bond element of the portfolio to fund withdrawals in the early years, leaving the theoretically higher growth equity part to increase in value. Depending upon market conditions such a strategy can be the complete opposite of traditional wisdom as the bond proportion of the portfolio can reduce - even to zero - during retirement. Analysis shows that these strategies produce higher safe withdrawal rates in most scenarios and in worst case are equal to strategies based upon fixed equity/bond ratios.
There is an appealing logic to these strategies as in effect one is saying that I have a chunk of money - maybe 50% of my assets earning very little (the bonds) so I´ll spend that first and let my stocks grow rather than eat into the assets which history has shown will grow in value. There are many variants of this strategy some of which avoid the perhaps worrying prospect of having a 100% equity portfolio during the latter part of one´s retirement.
That´s Why I´m Moving Away From Life StrategyFunds
Two simple reasons - (i) the presence of non-government bonds in the funds (ii) the probability that I will adopt a drawdown method that has dynamic equity/bond ratios meaning I need to separate holding of stocks and bonds.

I look forward to reading your conclusions for the UK investor.
